Question

Write two applications of projectile motion

Answer 1

• The applications of projectile motion in physics and engineering are numerous. Some examples include meteors as they enter Earth's atmosphere, fireworks, and the motion of any ball in sports. Such objects are called projectiles and their path is called a trajectory.

Answer 2

Answer:

(ii) 2x2y + (- 4x2y) + 6x2y + (- 5x2y)

= 2x2y - 4x2y + 6x2y - 5x2y

= (2 - 4 + 6 - 5)x2y

= (8 - 9)x2y

= -x2y
